\section{Intervention strategies to prevent diffusions}
\label{sec:intervention}
In this section, we study how to design good intervention strategies
to control harmful diffusion processes. We characterize intervention
strategies into two categories, centralized and decentralized. Both
kinds of strategies share a common mathematical framework, which we
define formally in Section \ref{sec:intervention-framework}. Then we
state our results and propose research for centralized and
decentralized intervention strategies in Section
\ref{sec:optimization} and \ref{sec:decentralized},
respectively. Lastly, in Section \ref{sec:behavioral}, we enrich our
intervention strategy designs with the consideration of individual
behavior changes.
